COAL-CHUTE.

SPECIFICATION forming part of Letters Patent No. 388,542, dated August28, 1888.

Application filed April 25, 188B.

To @ZZ whom it may concern: ,n

Be it known that I, JOHN H. DU Bois, of Hoboken, in the county of Hudsonand State of New Jersey, have invented a new and Ixnproved Ooal-Ohutefor Loading Vessels, of which the following is a full, clear, and exactdescription. l

The object of my invention is to provide a I chute whereby coal may beloaded from a high coal-dock into a vessel below without pu1verizing orbreaking the coal; and the invention consists of the construct-ion,arrangement, andcombination of parts, all as hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the Iigures.

Figure l shows my invention lowered by the boom in position for use, aportion of the coal dock and chute being broken away. Fig. 2 shows theboom and chutes in elevated position; and Fig. 3 is an enlarged detailedsectional view of one of the hoppers, showing the same provided with anadjustable plate and adj usting-screw, which may be used or not, asdesired.

The dock A with its fixed chute A may be of the usual or of any approvedconstruction. Mounted upon the dock A is the mast B and the windlass C,the latter for elevating and lowering by rope O the chute D, hinged tothe lower edge of the fixed chute A. Connected' to the outer end of thechute D by means of the arms d d and links d' are the series ofconnected hoppers E E. The lowermost hopper is connected by rope F tothe boom G and mast B, said rope passing over the pulleys f j", attachedto the boom and mast, respectively, so that by drawing upon the saidrope F the whole series of hoppers E may be inverted, or

one or more in succession, as indicated in dot- Sclial No. 271,760. (Nomodel.)

ted lines, as the filling up of the vessel proceeds. The hoppers are allconnected together by4 pivoted links g, and their lower open ends" sothat all breaking of the coal is obviated. y

As the filling of the vessel proceeds, the hoppers E will be lifted outof the line by drawing upon the rope F, as indicated in dotted linesinFig. l, the links g'permitting the hoppers to be inverted, as shown inFigs. 1 and 2.-

In each of the hoppers is placed a plate, E', acted upon by anadjusting-screw, El, so that by turning said screw the discharge fromthe hopper may be regulated according to the size of the coal to beloaded.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the chute D, ofthe series of tapering hoppersE, connected together by the links g, of sufficient length to hold thelower end of each hopper above the upper end of the adjacent hopper,whereby the series of hoppers may be swung out of action one at a time,substantially as described.

2. Thehinged chute D,having the connected series of hoppers E, incombination with the boom G, mast B, rope F, and pulleysff, substantially as described.A
